EP,
Minor, minor note to your spreadsheet. Possibly change B7 from '# of JV's' to something like '# of JV P2O machines'. No big deal, but as I was reading the sheet, it looks like column B is the number of JV's, not the total quantity of all machines at all JV locations.
I predict future happiness for Americans if they can prevent the government from wasting the labors of the people under the pretense of taking care of them.
